Hi Glen, Parallel environments (PE's) are "mostly" the same in Grid Engine 6 vs 5.3 in my experience. The main "gotcha" difference is that in SGE 6 you tell the *qeueue* the list of PE's it is able to support while in SGE 5 the opposite occured -- the PE itself was configured with a list of queues that it was active in. The other addition is the "urgency_slots" param (I think) which was not in SGE 5.3. If you had PE definitions or deployment scripts that worked in SGE 5.3 but not in 6 it may be due to the above. The "pe_list" parameter has moved from the PE object itself and into the queue configuration. For SGE 6 there are still the usual PVM and MPI templates and examples that come with the distribution. Just look in $SGE_ROOT/pvm/ and $SGE_ROOT/mpi/. Reuti also just updated the Grid Engine tight LAMMPI HOWTO which is here: http://gridengine.sunsource.net/project/gridengine/howto/lam-integration/lam-integration.html Back to PE's ... This is what a generic loosely integrated MPICH PE would look like in SGE 6: > workgroupcluster:~ admin$ qconf -sp mpich > pe_name mpich > slots 512 > user_lists NONE > xuser_lists NONE > start_proc_args /common/sge/mpi/startmpi.sh $pe_hostfile > stop_proc_args /common/sge/mpi/stopmpi.sh > allocation_rule $fill_up > control_slaves FALSE > job_is_first_task TRUE > urgency_slots min Note that there is no list of queues that the PE runs in. This has moved. The "pe_list" is now part of the queue configuration: > workgroupcluster:~ admin$ qconf -sq all.q > qname all.q > hostlist @allhosts > seq_no 0 > load_thresholds np_load_avg=1.75 > suspend_thresholds NONE > nsuspend 1 > suspend_interval 00:05:00 > priority 0 > min_cpu_interval 00:05:00 > processors UNDEFINED > qtype BATCH INTERACTIVE > ckpt_list NONE > pe_list make mpich > rerun FALSE < ....
